Debugging application performance over a network

摘要: An application debugging switch also monitors performance. The forwards the requests from a first host to second host, and later response coming that host. As most of applications work in request—response architecture, can measure time application. attaches timestamp each request it forwards. When comes switch, determine collects multiple samples over certain period time. These provide good measurement for average is combination network holds classes. Each class defines different sources or destinations traffic (IP addresses networks) (TCP/UDP ports content identifiers requests). Collecting separately allows zooming an user experience bad service detect reason their failure.
